- Acyl transfer (nucleophilic substitution at carbonyl) reactions proceed in two stages via a "tetrahedral intermediate." Draw the tetrahedral intermediate as it is first formed in the following reaction. H3C HCI / H2O `NH2 reflux • You do not have to consider stereochemistry. • Include all valence lone pairs in your answer. • Do not include counter-ions, e.g., Na", I, in your answer. • In cases where there is more than one answer, just draw one. opy aste Previous Nextarrow_forwardIdentify the major product of the reaction of an alkene shown below. ||| 1.

I know that for addition of halides on alkene double bonds, there are Markovnikov products becasue of 1,2-halide/methyl shifts, but there usually aren't shifts in hydration reactions. Essentially, would the Markovnikov/major product for this reaction have a hydroxy group attached to the tertiary carbocation and the anti-Markovnikov/minor product for this reaction have a hydroxy group attached to the adjacent secondary carbocation?arrow_forward
- Researchers have been able to conduct sequential ring closing metathesis tollowed by a cross-metathesis reaction, in an effort to create rings and add carbons. However, cross-metathesis can be challenging when there are strained alkenes present, as shown in this example with a final product of 8%. Fill in the missing structures from each reaction.
